balloon card yugioh YU-GI-OH! - Wonder Balloons (NECH-EN055) - The New Challengers - 1st Edition may be 1st or Unlimited Edition Wonder Balloons - Duelist Alliance:

It was a set designed to explore mechanical spaces that normal sets did not at the time

So much so that the card is already being eyed up for cEDH lists by high-level players

It will come with: 8 foil Pokmon TCG cards with a festive stamp 5 Pokmon TCG booster packs 7 Pokmon TCG 3-card fun packs (they contain three common cards, one of which is a reverse holo) 2 Pokmon coins 2 Pokmon sticker sheets 1 sidekick dangler featuring Pikachu and Glaceon Plus, find a code card for Pokmon TCG Live

Thus a card that dominated the formats it was legal in or has regular play in Modern or Legacy like Atarka's Command, Wild Cantor, Burning-Tree Emissary, Huntmaster of the Fells, Manamorphose, or Bloodbraid Elf, would still need to prove it's chops at the kitchen table
